This operation, of course, frotates the #wheel flinfaccordance with ,40 the speed "lof ithe' ',yarn yand ithe'refore the 'wheel iilicanl be" cons'ideredfas'the: motive power for this measuring 'fm'achine. 11n fthe :present instance tri-is'lwhel iisYshoWn as f made of :such "a diameter as'ftofhaVeithe-l circumferenceaI .quarter Aof a yard andonelrota'tion measures al quarter yard.

.The `wheel -ilil "isimou'nted on fa shaft Il in `closedibearin'gsbnahollow''extension i12 fromv a circularverticalfcasing flr3. This'casing is entirelyfenclosedf-and-thewextension also so that v.50 :there is'fno opening for the-entrance of lintand dust.. Cnet-he shaft is-a vworm I4 which drivesl -afwormwheelLilgasusual. The number of teeth on the wheel iacontrols the-number of `its rotations relative to those of the shaft H.

'Ihe worm Wheel |5is supported by,but not xed to,a shaft I6,onwhich thewheel is freelymounted. This shaft I6 has a bearing in the back of the casing I3. In order to reduce the friction of the wheel I against the casing or against a washer or the like, the casing is shown as provided with an annular convex integral projection |1 at the back against which the wheel I5 bears. 'I'hus there is only a small bearing surface and yet the wheelis heldlagainst motion backwardly beyond the desired point.

On the other or front side of the wheel I5 is an annular projection I9. Within this projection is a circular clutch disc 2U. 'I'his clutch disc is perforated at the center so that it will have no bearing on the shaft |6, and is provided with a radial slit 2|. Diametrically opposite this slit is a slot 22, shown of circular form, and lined by a spring 22a so that only a thin piece of metal is left to connect the two halves of the disc beyond this slot. The disc is rendered flexible to that extent. The disc is also provided with another radial slot 23 byY which the disc can be turned. Obviously. if some instrument is inserted in the Y slot 23 and pushed in oneV direction, that is, the

direction away from the nearest wall of the slit 2|, it will expand the vclutch disc and prevent its turning inl the circular space by increasing the friction of the circular periphery of the disc against the wall of the space in which it is located. l'f it is vpushed in the other direction, it will contract the disc, Vrelieve the friction, and the disc can be turned in that direction only. vThe power is transmitted from the gearA |5 through this clutch disc in one direction only.

The parts so Vfar described are shown in my above mentioned patent with the following exceptions: Y

'Ihe casing, including the extension I2, is made dust-proof, that is, there are no openings in it through whichdust andlint can enter the casing. This is accomplished without any special features by having the shaft |I fit a circular hole in the extension to obviat'e any opening at this point while the shaft does not pass through the extension at the other end. Anotherfeature that is different is the fact that the clutch disc is arranged to rotate in the opposite direction to that shown in the patent. This is for the purpose of permitting the pointer |8 to move along the circular scale on aY dial 24 from the point at which it is originally set at the left of the zero point and moved'around the scale in a clockwise direction to the zero point and stop, as will appear. The direction of rotation in the patent above mentioned was opposite-to this.

On the shaft I6 is xed an operating disc 25 which has an eccentric pin 26a entering the slot 2,3. Thus the shaft I6 is directly driven. Therefore, the rotation vof this clutch from the shaft Ywill also positively rotate` the operating disc butin one direction only. Thiszdisc'is provided with two teeth.26 and 21 (see Figs. 4 and 5). The tooth 26, once during each complete revolutionY of the disc, engages a pinion28 and turns it through the space of one tooth. This pinion is fixed to a shaft 29 which fixedly carries a second pinion 30, which pinion meshes with the circum- Y fervential teethl on a mainV gear 3|.

Thus the tooth k2,6 indirectly but positively rotates the pinion' and the gear 3| step by step. 'Ihis gear is fixed to a tubular shaft 3 |a freely mounted on the `shaft I6; Thus the `shaft 3|a is intermittently rotated with thegear 3| operated by the clutch 2U.

The shaft 29 (see Fig. 17) with its two pinions, is mounted on a lever 32 which is pivoted on a stud 33 carried on an outer plate 34 which is mounted in stationary position at the front of the casing and xedly carries the dial 24. This lever 32 is provided with an end 35 against which bears the end of a spring 36 that is wound on the stud 33 and is provided with an arm having a small coil 31 which engages the teeth of the pinion 28 and prevents that pinion from moving more than one tooth at a time and always holds the pinion in place after it has been moved. The lever 32 is provided with two notches 38 and 39 which engage a tooth 4I) on a lever 4| pivoted on a stud 42 also carried by the plate 34. Behind the lever 4| is a spring 43 which holds it up so that the tooth thereon will hold the lever 32 by either of the notches 38 or 39 according to the position of that lever. The lever 32 has an arm 44 by which it can be manipulated, as will be seen. -The lever A32 has a projection 32@- which will be engaged by a pin 60 on the gear 3| to' throw the lever 32 from the position shown in Fig. 1l to that shown in Fig. 17 and the pinion out of mesh with the gear 3|.

Up to this point it will be seen that the rotation of the shaft I6 through the clutch 20 will rotate the main gear 3|, while in mesh with the pinion 30, constantly but intermittently with a slow motion. Y

The operating disc 25, as stated, has a tooth or projection 21 which is bent out of the plane of the tooth 26 and at a certain time, as will be described laterengages the arm 44 so as to swing they lever 32 back toward the gear 3| after itl has been thrown out of operation and thereby start operation again. The tooth 21 and projection 44 are so located relatively as to contact only when the lever 32 is in a position in which the pinion 30 and gear 3| are disengaged, as shown in Fig. 17.

Fixedly mounted on a collar 5I centered and rotatable on the shaft 3|a is a stop disc 45 having one tooth 46 (see Fig. 9). This disc is provided with a stud 41 to which is connected a flat coil spring 48 which is also connected at the other end with a stud 49 on the main gear 3|. This spring 48' urges stud 5|) into engagement with the tooth 46, the rotation taking place when the pinion 3|.'I is moved out of contact with the main gear 3|.

The collar 5I extends through the plate 34 and dial 24 and has at the front end a thread for receiving a nut 51. Behind the nut is a disc 58 (Figs. 15 and 16) having an integral key 63, or other means, for causing the collar 5I to turn with it. This disc 58 has a handle 62 slightly bent outwardly for convenience in operating it. When the nut is loosened the stop disc 45 .can be Yturned by the handle 62 to adjust the stop disc. It is fixed in adjusted position by screwing down the nut by a spanner not shown. When this is done the stop arm 45 is held in stationary position against the surface of the plate 34.

The Yhollow shaft 3 |a extends through the plate 34 and the dial 24 and has at its outer end a flattened portion 52 (Fig. 1) on which is a disc 53 with -an oblong opening fitting the flattened portion of the shaft. The pointer I8 is carried by the disc 53 and preferably is integral with it. Initially, to set the machine, this pointer is moved counterclockwise ltoV the point on the circular scale that indicates the number of thousands or hundreds of yards to be wound to form each package. The turning of the pointer I8 carries the pulley, an operating disc xed to said shaft, a

tatable therewith, a gear concentric with the shaft but rotatable freely thereon, a pivoted lever. having means adaptedto be operated by said disc once during each rotation of the operating disc for rotating said gear intermittently, and a pin on the gear in position to engage the lever, to swing it so thatsaid operating means is disconnected so that the gear is free from itsY operating means. f
